I am going to install FreeBSD on a machine we plan to make a server.
Now, we have 2 lines of internet coming to our place through 2
separate lan modems. I want the server to take these 2 lines and
combine the speeds to form a single line which can be used by our lan
to access the internet.
I have got 3 lan cards on the linux machine. 2 for the incoming
connections from the 2 lan modems which have the gateways
192.168.1.1<http://192.168.1.1>
and 192.168.1.100 <http://192.168.1.100>.
How do I go ahead with making my server a gateway offering combined
bandwidth to our lan?
I'm not sure I understand your message, but:
How do you do it with the Linux machine?

That doesn't do what you described. That's just regular bridging, to
connect two links into a single subnet. FreeBSD can do that quite
well (there's a whole chapter titled "bridging" in the FreeBSD
Handbook), but it doesn't have anything to do with load balancing
across the two links, which is what you said you were after.
I think Lowell is right; bridging is not routing and is not going to
load balance your ISP links. Even if you figure out how to make
FreeBSD route your outbound traffic as if the two lines were one, it
cannot really work unless both lines go to the same ISP router and
they cooperate with you. They'd have to configure their router to
treat the two lines as one, to load balance your inbound traffic.
For example, we have multiple ISP links (one fiber optic and two T-1
lines) all from the same ISP. The two T-1 lines are configured with
load balancing to effectively form a combined 3 Mbps link (but this
is done with Cisco IOS, not FreeBSD).
Even though they all go into the same router on our end, the two T-1
lines cannot be load balanced with the fiber link because the fiber
and T-1 lines end in two different ISP routers on the far side
(actually in two different POPs). So, we just have the ISP router
configured to use the fiber if it's up, or to use the combined T-1's
if fiber goes down.
